False Feeding

FALSE FEEDING, feeding of an animal (dog) with a gastric fistula and esophagotomy. The method was proposed by I.P. Pavlov (1890). The food eaten falls out from the upper end of the severed esophagus, not entering the stomach. Brief false feeding produces abundant 2-4 hour secretion of gastric juice with high digestive power (acidity and digestive power are higher than with irritation). The latent period is 5-10 minutes. Secretion is insignificant with false feeding of liquids (milk, broth); there is no secretion with false drinking of water. Unfamiliar manipulations, showing a cat cause cessation of secretion (an easily inhibitory reaction). The same regularities were observed in humans (cases with esophageal obstruction and gastric fistula). There is no secretion to rejected and indifferent substances. -Feeding of the operated animal: food is introduced into the stomach through the fistula, water - by probe through the lower opening of the severed esophagus. -Scientific significance of the false feeding method: clarification of the mechanism of gastric secretion. Practical application - obtaining natural gastric juice for therapeutic purposes without admixture of food and saliva. To obtain a large amount of juice, false feeding should continue for several hours.
